Step & Wall Flashing
Lead step flashings and wall abutment flashings replaced for a permanent, watertight seal.
- Chased into brickwork at correct depth
- Proper overlap with tiles at every course
- Fixed pricing with no hidden extras
Where Roof Meets Wall Is Where Leaks Begin
Wherever a pitched roof meets a wall — lean-to extensions, side abutments, conservatory roofs meeting the house — lead step flashings and cover flashings seal the gap. These junctions are under constant stress from thermal movement, and over time the lead pulls out of the chase line or lifts away from the tiles. Once the seal breaks, water runs down the wall and into the roof structure, causing damp, staining and timber damage.
Radiant Roofing replaces step flashings and wall abutment flashings across Kent, Sussex and Surrey. We rake out the old chase, fit new lead stepped and dressed to each tile course, and repoint with a flexible sealant that accommodates movement. Every flashing is fitted to last decades, not years.

Frequently Asked Questions
Step flashing replacement typically costs between £250 and £1,500 depending on the length of the wall junction and access requirements. A short lean-to run costs £250 to £500 from ladder. A full two-storey side abutment requiring scaffold runs £800 to £1,500. We always provide a fixed quote after inspection.
Step flashings follow the stepped profile of a pitched roof where it meets a wall — each piece overlaps the one below, matching the tile courses. Cover flashings are continuous strips used on straight horizontal junctions. Both are chased into the brickwork and sealed. We fit whichever type is correct for your roof geometry.
We do not recommend it. Self-adhesive flashing tapes are a temporary repair that typically lasts three to five years before peeling away. Properly installed Code 4 lead sheet lasts 50 years or more. For a permanent repair, real lead is always the right choice.
